Go package and CLI tool for listing OUIs.

...The manuf CLI tool can be used with tools like grep and jq to filter results. Records are fetched over HTTPS on first use
from manuf.csv, which is then cached in a local directroy,
/Users/$USER/Library/Caches/manuf.csv on macOS. After 30 days, the records are fetched again to refresh the cache.
